Prince William probably won't be Prince Harry's best man

For Prince William’s wedding in 2011, he called on his younger brother to be his best man. So when Prince Harry marries Meghan Markle in May, will he return the favor?

Acording to one royal expert, that might not be the case. Apparently, there’s actually no such thing has having a best man at a royal wedding — but William broke protocol to honor his sibling when he wed Kate Middleton.

Marlene Koenig, British and European royal expert, told Town & Countrythat “the best man or best men are officially called supporters.”

She did add that “William will probably be Harry’s supporter,” carrying on the sibling tradition that was also displayed by the brothers’ father, Prince Charles. For his wedding to Princess Diana in 1981, he chose his brothers, Edward and Andrew, to be his “supporters.”

It’s also likely that William will plan his younger brother’s bachelor party. Although William’s affair was kept well under wraps, a royal insider told Brides that Harry hosted his brother’s “at a country estate about a month before the wedding.”

As for the rest of the wedding party, Prince George and Princess Charlotte will likely serve as page boy and bridesmaid, respectively, Koenig noted, but “anyone else is a guess.”

Markle’s bridesmaids are also a mystery. While many expect her A-list friends such as Serena Williams and Priyanka Chopra to be invited to the nuptials, it’s likely the royal family will want to steer clear of a celebrity wedding.
